On the information entropy of matter-waves in quasi-disorder potentials
arXiv:1710.05632 · doi:10.1140/epjd/e2018-90259-7
Abstract
We consider ultracold Bose gases in quasi-random potentials and quantify localization of matter waves by means of Shannon information entropy. We explicitly examine the role of quasi-random potentials in producing localized states in the linear and nonlinear regimes. It is seen that the information entropic-based approach can be more useful to quantify localization of different types of states observed in Bose-Einstein condensates.
